Elevated levels of tumor markers were detected in 24 cases (45.28%), including AFP (Alpha‐Fetoprotein) (n = 9, 16.98%), CA19‐9 (Carbohydrate Antigen 19–9) (n = 7, 13.21%), CA125 (n = 3, 5.66%), NSE (Neuron‐Specific Enolase) (n = 3, 5.66%), CEA (Carcinoembryonic Antigen) (n = 1, 1.89%), and CgA (Chromogranin A) (n = 1, 1.89%). This evidence concerns the gene CGA and neoplasm.
